摘要： Spinal implant trials are provided having various configurations and sizes that aid the selection of spinal implants having similar configurations and sizes. A surgeon during surgery can insert various configurations and sizes of the spinal implant trials into a disc space between two adjacent vertebral bodies of a patient to enable the selection of a spinal implant configured and sized to fit the patient's disc space. Fluoroscopic images can be used in aiding the selection of an appropriately configured and sized spinal implant corresponding to one of the spinal implant trials. The spinal implant trials include features that reveal on the fluoroscopic images whether the spinal implant trials are properly located and oriented in the disc space and include features corresponding to different sizes of spinal implants also revealed on the fluoroscopic images.

摘要： A spinal implant for insertion into a disc space between an upper vertebral body and a lower vertebral body is provided. The spinal implant includes an upper first end plate portion and a lower second end plate portion each extending from at least adjacent a proximal end to a distal end of the spinal implant. The spinal implant is configured to facilitate insertion into the disc space and inhibit withdrawal from the disc space. To the end, the leading end of the spinal implant can be configured to facilitate ease of insertion into the disc space, and an upper surface and a lower surface of the upper first end plant portion and the lower second end plate portion, respectively, can be provided with depressions or dimples forming ridges and points therebetween to inhibit withdrawal from the disc space.

摘要： An expandable interbody implant adapted for insertion at least into a disc space, between two adjacent vertebrae of a spine. An upper member and a lower member are pivotally connected at least by a drive link. A bone graft storage portion packed with a selected volume of bone growth material. A translational wall is provided between the bone graft storage portion and a trailing end of the implant. An actuator engages the bone graft storage portion, pushing it forward into engagement with the drive link, which pivots upward, moving the upper member upward away from the lower member. Upward movement of the upper member raises the translational wall to a position to assist in retention of the selected volume bone graft material within the hollow portion of the bone graft storage portion. Upward rotation of the drive link brings a face thereof into contact with a front of the bone graft storage portion, thereby retaining near constant volume of the bone graft material.

The spinal implant trials include features that reveal on the fluoroscopic images whether the spinal implant trials are properly oriented and positioned in the disc space. As such, the selection of the configuration and size of the spinal implants can be made after it is determined that the spinal implant trials are properly oriented and positioned within the disc space.

摘要： A surgical instrument comprises a member connected with a spinal implant defining an axis. A first image guide is connected with the member and oriented relative to a sensor to communicate a signal representative of a position of the member. A second image guide is connected with the member and oriented to represent an angle measuring a second orientation of the axis relative to a first orientation. Systems, implants and methods are disclosed.

摘要： A geared cam expandable spinal implant. Rotational motion of a rotating portion is translated into linear motion of a yoke, which moves geared cams at the distal end of the implant to mate with, and walk along, teeth of corresponding racks. The walking of the gear cam teeth along the rack teeth creates a regular rate of implant expansion, reduces initial excessive expansion force applied to the implant, and provides fine adjustment of the expansion rate and force.
